JULIUS HARRIS, F LIVERPOOL, ENGLAND, ASSIGNOR EMERY,

SOUND RECORDING AND REPRODUCI NG MACHINE.

To altwhom it may concern;

Be it known that I, JULIUS HARRIS, a sub;

'ject of the Kingof England, residing at more easily worked and atthesame time the mechanism is simple,'inexpensi ve, and eife'c tive, andcapable of giving uniform and reliable results records, and in playingthem.

, This invention will be described with the aid of theaccompanyingdrawings, which I illus'tr'atean auto-muslcal instrument of thecharacter herein'referred .to, and in which "the improvementshereunderare comprised.

In these drawings, Figure 1 is a plan of one part, and Fig. 1 a plan ofthe other part of the improved mechanism, and Fig. 2 is an elevationpartly in section of the improved mechanism. Figs. 3,4, and 5 aredetails hereinafter described, and Fig. 6 shows a part of the handactuating means,

1, generally designates a rocking frame; 2 is a spindle on which therecord table 3 is mounted; 4 is a pivoted spindle on which the frame 1is mounted and about which it rocks; and 5 is the usual springmotorwhich is wound up by the movementof the frame.

The frame 1 has connected with it a lever 6., which is hereinafternected with the spring motor 5 by a chain 7, one end, of which isconnected up with the frame itself, and the other with the case 8ofthespring motor 5'; while one end of the spring is'connected to thecase, and the other with an arbor 9, which has fixed on it a toothedpawl wheel 10, which isheld against rotation in one direction by thepawls 11.

The frame 1 carries gearing by which motion is imparted to thercordsdisk and the or effects, both in the taking of actuated hand in themanner described; and the frame is con I Specification of LettersPatent. Application filed September 2, 1909., Serial No.

mechanism connected with the same through a fixed curved rack 13, whichis attached to the carrier bed 14 of the machine, and held stationarythereon. This rack serves to operate the gearing carried by the frame 1,through a part of the said gearing engaging with such rack and beingcaused to travel over it by the'spring motor 5 which is connected withthe frame 1 by the chain 7.

The gearing carried by the frame com-. prises a tooth wheel 15 whichengages with the curved rack 13, and as the frame is moved by the springmotor 5' through the chain 7, the tooth wheel 15 is rotated by the teethof the curved rack 13, and the spindle 16 of the tooth wheel alsorotated, and such rotation of'the spindle 16 bevel wheel 20 throughratchet wheel 19 fixed to the spindle 16 and a spring pressed pawl 18attached to the wheel 20, and which engages with the teeth of the-saidratchet wheel 1.).

The ratchet wheel pawl 18 are provided for the purpose of enablingthespring motor 5 being wound without operating the gearing, that is,when the framel is rocked on its spindle 4 away from the spring motor 5the gearing carried by the frame is freed that is. the spindle 16 andratchet wheel 19, rotate freely owing to the pawl 18 slipping over theteeth of-the ratchet wheel. p The rotation of the bevel wheel 20transmits motion to the bevel pinion 21, andspindle 22, and the spindle22 rotates the spiral tooth 'wheel 23, and a worm 24 on the record disktable spindle 2; thus motion is imparted to the said toothed wheels andspiral and worin gearing, by causing the tooth wheel 15 to move over andin engagement with the stationary rack 13 by the spring motor 5,

the medium of a and the record is rotated at the required speed, whichis regulated as next described. The speed of rotation of the disk andits is transmitted to the 19 and spring pressed spindle 2 is regulatedby the governor device 12 more particularly shown in Fig. 3.

This device is of the well known characterand is driven through thetooth wheel 25 mounted on the record table spindle 2, and a tooth pinion26 gearing therewith and mounted on the spindle of the governor 'de'lower end which acts directly upon a pin 32 attached to the outer end ofthe lever 29. The end 28 of the lever 29 is normally pulled away fromthe disk'27 by the spring 33, attached at one end to the lever 30, and

at the other end to a part of the casing, and when the end 28 is-to bemoved toward the disk, the nut 31 is screwed farther on to the screwthreaded end of the spindle 4, and

rocks the lever 29 about its ivot 30 in such.

a manner as to move the en 28 of the lever toward the disk 27. The end28 serves as a braking device for the disk 27, that is, when -the disk27 is pulled downwardly by the weighted spring armsof the governor, thedisk bears against the end 28, and the speed of rotation is checked orreduced thereby.

The end of the lever 29, may have an antifriction roller or ball uponit, which works in connection with 'the under side of the disk 27.

The sound box is mounted on gimbals as shown in Figs. 4 and 5, to givelateral play or movement and the proper adJustment and the needle willbe pressed onto the record disk 10 by gravity, or by a. slight spring.

The gimbals consist of an inner ring 38, to which the sound box tube 37is connected by pins 39; and the ring 38 has pins 40 on it, which aremounted in the outer ring 41 directly connected with the trumpet tube42, which will be fixed or stationary, and is without a sound arm. .Bythis arrangement, it will be noted that the sound box 35 will havelateral play as wellas vertical play, and the needle is free to followthe impressions of the disk readily and accurately.

With regard to the spring 5, this may be of a single type, or consist oftwo or more laminae or springs.

The whole apparatus and parts described are mounted upon a suitable box,table or base 45; and the actuating lever 6 is preferably operated by ahand crank lever 46 on the outside of the box, which is connected upwith the lever 6 through a spindle 47,

a drum or wheel 48 upon it, and a chain 49 which wraps around the drum.By moving this lever 46, say about half a revolution, the frame 1 willbe completely moved from its terminal position to the starting position,that is, it will be fully set, so that upon remeans for regulatinglease; the eompleteaction of the mechanism and record table will follow.

The winding of the motor spring, and the setting of the instrumentgenerall is effected by rocking or moving the me or part carrying thespindle on which. the record table is mounted, away" from the springmotor; and when this-frame is released, the spring which has been woundup returns or moves backthe frame, and drives through the said toothedand other gearing and the stationaryrack, the record spindle and recorddisk.

As the frameand gear are moved or actuated by .the spring motor the diskwill be moved relatively to the style or needle of the sound box; andthe record will traverse therefor under the style or needle.

What is claimed is 1. In a sound reproducing or recording machine, apower motor, a recorddisk table,

and a movable record table carrying part,

. having a flexible connection with the motor,

whereby the latter is wound up when said part is moved in one direction,and said part is moved in the opposite directlon by the motor when thelatter is released;
